My Adventure of the Seas trip report.
Day One - Puerto Rico
We headed to Detroit, Saturday night and stayed the night in a hotel there before our flight out on Sunday morning. The flight was delayed 45 minutes because the ground crew couldn't seem to figure out how to put suitcases into the airplane

I think the pilot was getting a bit peeved at the whole situation. Anyways we finally got airborne and made pretty good time, arriving in San Juan only about 1/2 hour late.
We retrieved our luggage and found our way to the
Royal Caribbean ground transportation. We boarded a bus and were on our way to the port in no time at all. First we had to put all our suitcases onto a truck that would transport them to the ship.
When we pulled up to the terminal there were HUGE lines of people waiting outside the terminal to register and board the ship

Because we took Royal Caribbean's transportation and had no luggage to check in, we were allowed into a special line which put us way ahead of everyone standing outside. We checked in, had our picture taken and boarded the ship.
First stop, our cabin on deck 9 to drop off our carryone baggage. While there we met up with our room steward. I used the washroom before we left for lunch and noticed ants on the bathroom counter

I told the room steward and he said he'd take care of it for us.
So off to lunch in Windjammer Cafe. It was of course very crowded but we found most of the rest of our group. We had not all travelled together but did all arrive within an hour of each of each other. By this time it was 5pm and dinner was scheduled for 6.
Even though we had no interest in dinner Rick and I headed off to the dining room on time. We had to go in what we travelled in because our luggage had not been delivered to our room yet. Most people seemed to be in the same situation.
Turned out we were the only two from our group that went to dinner that night. A table for 12 for 2 people
Did some exploring, saw the evening show ( a comedian who was forgettable), came across our travelling companions and visited for a bit, checked out the buffet snacks

and then headed off to bed around 1am.
A very long and interesting first day.
